To all whom 2'25 may 00mm Be it known that 1. MICHAEL W1LsoN a citizen of theUnited States, and resident of.

the borough of Brbokly'n;'county of Kings city and State of Newx lorlr, have invented certain new and useful Improvements in lVinr'low Guards.

This invention relates to improvements in window guards and has for its principal object to provide a device which may be readily attached to a window so that when the window is open the passage is barred, thereby preventing the entrance of sneak-thieves and other unauthorized persons.

Another object of the present invention is to provide a device which will effectively prevent children from falling out of an open window.

A further object of the invention is to provide a guard which may be readily released from the interim: so that in case of fire escape through the window may be made.

lVith these and other objects in view the invention consists of a novel construction, combination and arrangement of parts which will be fully set forth in the following specification, claimed and illustrated in the accompanying drawings in which Fig. 1, is a face view of the window illustrating this guard attached thereto showing portions of the sash broken away to more clearly illustrate the details of construction.

Fig. 2, is a vertical sectional view through Fig. 1.

Fig. 3, is a sectional view through one of the securing elements by which the guard is held in place and Fig. i, is a fragmentary view partly in section of the upper sash illustrating the locking means therefor.

Referring to the drawings in detail the numeral 5 designates the wallof the building in which the window is mounted and this wall 5 is provided with a pocket 6 as, is customary The gu ardis designated in its entirety by the numeral 12 an dcomprises the u-pperbar 13'and lower bar 1 f which are connected by vertical fillers 15 which are adapted to slide through openings 16 in the sill 17. V ticaL ly extending supporting-bars 1d are secured adjacent opposite ends of the bar 13 in alignment with the bores 11 and said sarpportihg bars are slightly longer than the side rails of the sash 9 and have their upper ends provided with screw threads upon which suitable securing nuts may be threaded.

While it is obvious that any suitable nut may be used in connection with the threaded ends of the bars 18, it has been found preferable to use nut which may be rapidly released so that in case of fire thewindow may be opened without raising the guard. To this end a nut such as illustrated in Fig. 3 has been designed which'comprises a hollow substantially spherical body 1.) provided with a bore 20 for the reception of the shank 21 of a press button 22. A. slightly enlarged bore 23 extends into the body 19 in alignment with the bore 20 and forms a seat for the inner end of a compression coil spring 2 the outer end of which engages the outer side of the button 22.

."ir ivotally mounted on a suitable shaft 2-5 extending horizontally through the hollow body 19 are jaws 26, the inner faces of which are threaded to match the thread on the upper ends of the rods 18 and these jaws are 28 of the inner endof the shank 21. It will be obvious that upon applying pressure to the button 22, the inclined faces 28 will engage the 'arms 2"? and thereby cause the jaws 26 to move outwardly so that the threads on the inner faces thereof will disengage the threads on the upper ends of the bars 18. in. this Way it will be evident that the guard may be released so that the window is left free to open-without moving the guard and thereby allowing for the esca e of the occupant-s of the building in case of fire.

In order to hold the upper sash against movement when the lower sash is raised a suitable locking bolt 29 isslidably mounted in a bore 30 in one of the side rails of the upper sash.

While in the foregoing there has been shown and described a preferred embodiment of this invention, it is to be understood that certain minor changes in the details of construction, combination and arrangement of parts may be resorted to Without departing from the spirit and scope of the invention as claimed.

What is claimed is z- 1. The combination With a window having a sliding sash, said sash having a groove in the outer face of one of its rails and provided with bores in the rails extending at right angles to the grooved rail, of a guard having it upper end seated in the groove in said rail, supporting rods extending through the bores and having certain oftheir ends connected to the guard and means to removably secure the rods in the bores.

guard and means connected to the upper ends of the supportlng bars to. niovably secure said supporting bars in the bores.
